When Aztec emissaries arrived in 1520 to Tzintzuntzan, the capital of the Tarascan Kingdom in what is now the Mexican state of Michoacán, they carried a warning from the Aztec emperor, Cuauhtémoc.
They cautioned that strange foreigners – the Spaniards – had invaded the land and posed a grave threat. The emissaries requested an audience with the Tarascan ruler, known as the Cazonci, King Zuanga. But Zuanga had recently died, most likely from smallpox brought by the Spaniards.
Relations between the two empires had long been tense. They had clashed on the western frontier since 1476, fighting major battles and fortifying their borders. The Tarascans viewed the Aztecs as deceitful and dangerous – a threat to their very existence.
